In combination with a Rohde & Schwarz compact DF antenna, the R&S DDF1555 DF system becomes an optimum solution for applications that require portable and mobile direction finders for use in outdoor environments. A comprehensive range of accessories further enhances the flexibility of the DF system. The R&S DDF1555 compact DF system relies on high- precision DF methods. It can be used as a mobile or portable DF system or as a temporarily deployed DF station. Thanks to its low weight and compact dimensions, the DF system can be set up and configured quickly and easily. It has a low power consumption, allowing a long operating time in battery-powered applications. The direction finder s integrated wideband receiver offers ample functionality for signal search and display, including a panorama scan function (option) for the fast scanning of wide frequency ranges and a fast spectrogram (waterfall) display. For mobile DF applications, the R&S DDF1555 is combined with an R&S ADD107 compact VHF/UHF DF antenna (20 MHz to 1.3 GHz) or an R&S ADD207 compact UHF/SHF DF antenna (690 MHz to 6 GHz). These a ntennas come with an integrated GPS module, an electronic compass and an optional magnetic mount vehicle adapter. Installing the portable direction finder in a commercial vehicle takes only a few minutes. For best DF accuracy and sensitivity in portable applications, the R&S DDF1555 can be combined with the R&S ADD307 collapsible VHF/UHF DF antenna. This combination delivers significantly wider coverage in the VHF range. The antenna s integrated GPS module and electronic compass allow for a quick and easy system setup.

5 High-precision DF methods Correlative interferometer DF method The R&S DDF1555 uses the correlative interferometer DF method in conjunction with an R&S ADDx07 compact DF antenna. In contrast to other direction finders using simple amplitude comparison methods, the R&S DDF1555 offers significantly higher DF accuracy up to class A in line with ITU recommendations. Single-channel interferometer DF method The correlative interferometer DF method is based on measuring the phase differences between the reference antenna element and the other elements of a DF antenna. To measure the phase angle φ between the signals of two antenna elements by means of a single receiver independently of the frequency and phase modulation of the signal to be measured, a patented method from Rohde & Schwarz is used. With this method the phase of one of the two signals is shifted in four steps (0 /90 /180 /270 ) in a quadrature multiplexer, and the two signals are added in each case. The receiver measures the amplitude of the sum signal after each phase shift. Inserting the four amplitude values obtained (A1/A2/A3/A4) into the formula (see diagram) This high DF accuracy relies on the precise measurement of the phase angles between the reference antenna element and the other elements. Measuring the phase difference between two signals normally requires two coherent receive paths. For this reason, most interferometer direction finders on the market use at least two receivers. With the R&S DDF1555, the two receive paths are coherently linked in the DF antenna using a patented method from Rohde & Schwarz. As a result, the singlechannel interferometer DF method implemented in the Rohde & Schwarz direction finder provides the same DF accuracy and immunity to reflections as delivered by direction finders with two or more receive paths without requiring additional hardware. For the R&S ADD107 VHF/UHF DF antenna, the WatsonWatt DF method is used in the frequency range below 173 MHz. This method offers high DF accuracy even for small DF antennas. yields the phase angle φ between the two signals. This measurement is performed for each antenna element. Most interferometer direction finders on the market use at least two receivers. The two receive paths must be in phase and need to be calibrated accordingly since otherwise the measurement time will be significantly extended. Moreover, the local oscillator signals need to be multiplied and distributed in-phase. This means that more hardware is necessary than with a single-channel interferometer direction finder: an additional receive path, in-phase multiplication and distribution of the local oscillator signals, a calibration signal generator, calibration signal distribution and an additional cable to the DF antenna for the calibration signal.

6 Support of various applications Mobile direction finding Faulty, poorly shielded or incorrectly set electronic devices can unintentionally emit electromagnetic waves and degrade or even disrupt radiocommunications. Consequently, it is necessary to quickly locate the building, or the specific room within a building, from which radio interference originates. Unfortunately, buildings of interest are often to be found in densely built-up areas. If radio interference occurs continuously or frequently, using a mobile direction finder is the fastest way to locate the interference source. Within minutes, the compact DF system based on the R&S DDF1555 can turn a normal vehicle into a DF vehicle, covering the frequency range from 20 MHz to 6 GHz. This vehicle makes it possible to find the right building in a timely manner. In addition, during the drive, the R&S MobileLocator software (with R&S RA LOC radiolocation module) automatically locates the source of interference with a high degree of accuracy. On-the-march operation Some applications require direction finding on the move. Using the R&S DDF1555X08 carrying holster, the R&S DDF1555 DF system can be carried by one person, and bearings can be taken on the move. Touchscreen operation is also possible with R&S RAMON software modules installed on the handheld tablet PC used for controlling the DF system. Settings are made more easily and can be conveniently displayed along with the map application that presents DF results on a digital map. Man portable DF station Temporary installation of an R&S DDF1555 DF system in a commercial vehicle. Short-duration radio interference can disturb other radio services. When that happens, the building that houses the radio interference source must be located quickly. Short-duration radio interference cannot be located using a mobile DF system, because the emissions are not long enough for homing in on the source. This situation occurs, for example, with public mobile radio (PMR). PMR devices are widely used today since they are readily available and can be operated without a license. They are frequently used for mobile applications; their emissions typically last only a few seconds. Short-duration radio interference originating from public mobile radios or other sources can be located using two or more compact DF stations with the R&S DDF1555. The compact DF antennas are mounted on lightweight tripods and installed temporarily at exposed sites, e.g. on the rooftops of tall buildings. Man portable DF station with the R&S DDF DDF1555_bro_en_ _v0201.indd :00:43

7 In such cases, a DF station often needs to be transported and set up by one person. A complete R&S DDF1555 based DF station can be accommodated in a backpack and carried up to a rooftop or to any other remote location accessible on foot only. Temporarily deployed DF station Special means are required when analyzing and locating radio interference sources and other emitters in the following scenarios: In areas where authorities cannot eliminate radio interference or monitor compliance with radiocommunications regulations In security-critical areas, such as airports, seaports and military bases In areas where certain radio services are not allowed and compliance with this rule must be monitored At major events, e.g. sporting events The R&S DDF1555 based DF system can be deployed and expanded flexibly. R adio interference and other signals are detected, analyzed and located in a timely manner. The compact DF antenna can be mounted on a mast to provide better sensitivity and coverage in rural areas or areas offering little or no infrastructure for monitoring and taking bearings. The integrated wideband receiver in the R&S DDF1555 makes it possible to scan the spectrum and identify, analyze and record signals of interest. If necessary, the compact DF antenna (R&S ADD107 or R&S ADD207) can be mounted on a vehicle roof in just a few easy steps and used to locate transmitters. DF stations can be networked, and radiolocation results optionally displayed on a map (additional hardware and software required). The R&S DDF1555 based DF system can be conveniently stored in a transport case. These applications call for the temporary installation of a DF system for detecting and locating transmitters and radio interference. Temporarily deployed DF station with the R&S DDF1555.

10 Signal analysis and classification Signals with analog or digital modulation up to 500 khz bandwidth can be analyzed by using the R&S DDF1555 in conjunction with the R&S CA100 signal analysis and processing software (additional PC needed). Monitoring of complete signal scenarios The R&S CA100 signal analysis and processing software provides an overview of a frequency range of interest using a high-speed spectral or waterfall display. Signals are automatically searched and intercepted in a user-defined range. R&S CA100 has an automatic detector that enables users to scan or monitor frequency ranges automatically for fixed-frequency and burst signals. The R&S DDF1555 performs the search by combining the panorama scan mode and the fixed frequency mode (FFM). Automatic detection, classification, demodulation and decoding of multiple signals R&S CA100 supports both the monitoring of known signals (demodulation and decoding to content level) and surveillance/search operation by automatically detecting signals of interest and performing a classification. A powerful classifier with well-established algorithms automatically detects numerous modulation types, transmission systems and signal parameters. Content is extracted based on the software s extensive library of demodulators, decoders and transmission systems.

11 Wide range of options and accessories Options R&S DDF1555-IR internal recording The R&S DDF1555-IR option allows measured data to be recorded and saved to the direction finder s RAM. Recorded data can be replayed at a later time for detailed analysis using the R&S DDF1555-CTL control software on a laptop/ PC. Recorded data can include audio data in WAV format (replay using e.g. Windows Media Player), I/Q data, and spectrum and spectrogram (waterfall) data. R&S DDF1555-IG internal GPS module and external GPS antenna With the R&S DDF1555-IG option, the internal GPS module s NMEA protocol sets the system time. The R&S DDF1555 direction finder s internal 10 MHz reference frequency can be synchronized to the pulse-per-second (PPS) signal from the GPS module. This increases the accuracy of the internal reference frequency to typically (or better). It also significantly increases the accuracy of the time stamp in the direction finder s output data stream to a value typically in the nanosecond range. The option can be used to determine the position of the direction finder. It is also suitable for use in TDOA based applications or as a hybrid system that employs both DF and TDOA for radiolocation. R&S DDF1555-PS panorama scan When equipped with the R&S DDF1555-PS option, the R&S DDF1555 traverses a user-defined frequency range at maximum speed in monitoring mode.
